Looking for any problems or recomendations from folks on Ariens model 1944 zero turn mowers vintage 2008. Kohler twin 19 hp courage motor and hydrostatic drive. Do they hold up well ? I'm a little leary regarding the hydrostatic drives holding up, but zero turn would be slick for the way I mow my lawns. Any thoughts / experiences from anyone? Looking @ a used one needing drive belt. Mel C.
